Hi
I am building a small engine water brake dynamometer. I have a wheat stone bridge load cell and a hall effect sensor for RPM. I need to get the signal in volts from the load cell, and the signal for the hall effect sensor converted to RPM, and output thru the USB of the UNO R3 to an excel spreadsheet. I would like to do it live, with a switch that I use to start the data collection and shut off the data collection. I would like the data tabulated in columns (one for voltage and one for RPM)
That said, I am asking the forum to offer suggested code and how/what I need to hook to the board.
I have the board powered with 9V battery source, and a printer cable to go from the board to the computer
Thanks for the help
